If anyone is interested in some references on 3D coding give a shout. I searched
around a bit for papers on 3D and 2+1D encoders, but my papers directory is in
complete dissarray. Ill just give a pointer to a paper on the most recent (and
most successfull) implementation of 3D wavelet coding Im aware of, hope someone
finds it usefull...
http://www.microsoft.com/CHINA/research/downloads/g-imedia/spli/IMG-3.pdf its a
2+1D approach with the twist that they do the 1D transform along motion paths,
with pretty impressive results.

I have papers a lot more applicable to the present state of Tarkin, as I
understand it, lost in a big pile... can anyone suggest a good PDF indexing
program? Acrabat Catalog is crap, especially given that a good amount papers can
not be text searched.
